Outer clamp type ultrasonic flowmeter four types of typical fault phenomena analysis and solution

by:KAIDI     2020-10-08
Modern industrial development has given rise to many new technology and new equipment, ultrasonic technology is one of the important one, ultrasonic wave in the industrial production of many industries and departments have applied, and are playing a more and more powerful force of wide rang, became an industry and a country an important aspect of economic and technical strength. In the industrial measuring instrument this piece, with the use of ultrasound technology is more and more mature, clip type ultrasonic flowmeter is also more and more used in industrial production and civil fields. And other instruments and meters, also can cause failure of clip type ultrasonic flowmeter, embellish of instrument science and technology co. , LTD. In the ultrasonic flowmeter industry engaged in the r&d and production for many years, in many industries have a user provides a mature and stable product and technical support, his own is the company we explain the cause of several common faults of ultrasonic flow meter and the corresponding solutions, hope can help to you. Liquid medium flow phenomenon: the pipe without output: failure analysis: 1, between the converter and signal transmission cable conductor by the two; 2, outside power supply did not meet or poor contact type ultrasonic flowmeter; 3, sensors, instrument piping, shell, end face has a leakage. Solution: 1, the thread; 2, good power supply, keep good contact; 3, repair the sensor. Liquid medium phenomenon. 2: the pipe flow of no output: failure analysis: 1, between the converter and signal transmission cable connection circuit; 2, signal cable to the electrode connection circuit; 3, electrode surface contamination or deposition insulation; 4, bad earth or open circuit. The solution: 1, connected cables; 2, open the sensor, in again; 3, scrubbing the electrode surface; 4, the bottom line. Three phenomena: the error of measurement is too large, failure analysis: 1, the zero point is too high; 2, not completely filled with liquid; 3, power supply distortion is too large; 4, bad earth. The solution: 1, to adjust the zero point; 2, improve the channel conditions, sensor is always full of liquid. 3, outer clamp type ultrasonic flowmeter to improve power supply condition, conform to the normal working conditions; 4, good earthed. Phenomenon: four large data output abnormal fluctuations: failure analysis: 1, the unsteady flow field; 2, through the sensor of the gas in the liquid, solid block; 3, outer clamp type ultrasonic flowmeter electrical connection in the empty pick up; 4, bad earth; 5, electrode leakage solution: 1, the transformation channel, or increase the installation of sensors; 2, normal phenomenon; 3, check the wiring, then good line; 4, good earthed; 5, repairs and sensors. In this paper by embellish instrument technology co. , LTD. Arrange release.
It isn't just about being on level gauge anymore–it's about maximizing the potential of the platform of manufacturing.
